代码不适用于C++中的泛型类型向量

我试图通过这段代码向服务器发送图像，但代码在void filesendcontvector&fnames方法中出现故障。我用void filesendcont char*fpath重载了这个函数。当我没有重载此函数时，我就能够发送一个图像，但当我重载void filesendcont vector&fnames时，它在主线client.fileSendfilenames；处停止。我试着找出这个问题，但没能找到

我无法运行您的程序并重现您面临的问题，因为您没有提供服务器代码

但是，我认为你在这方面有问题：

string path = "C:\\Images:\\";

可能是这样的：

string path = "C:\\Images\\";

我纠正了这件事，但我一直面临着同样的问题。
